What is Wi-Fi calling?

A:

Quick Answer

Wi-Fi calling is a method of placing calls on a mobile phone over a wireless network as opposed to a cell network. The solution is based on an application from Kineto Wireless, a California-based, venture-backed company that enhances and extends communications services over IP-based networks like the Internet.

One benefit of Wi-Fi calling is better mobile phone coverage. Users can make calls and send text messages in remote areas, where the cellular coverage may be spotty, as long as there is a wireless network available. Another benefit is users can avoid cellular network charges by taking advantage of free Wi-Fi in public places. A mobile device must have the technology preloaded; it cannot be downloaded like an app. As of 2014, several telecommunications operators worldwide offer Wi-Fi calling services, including T-Mobile, Orange UK and the Canadian company Rogers Wireless.
